' l or roL n joHIqACOREOBATIO OF O O Y T I ADJUSTABLE eA'sBimNEn' Application filed February 16, 1931. Seria1No.' 516,010.

This invention relates to an adjustable gas burner which is primarilyadapted to be used in a furnace or heating plant. The general object of the invention-is to t provide a burner which may be expanded or contracted in such a manner as to fit fire pots of varlous s zes.

oblong fire pot, includes oppositely disposed manifolds in spaced parallelrelation and so mounted that they may be adjusted toward or from-each other inaccordance withthe width of the particular fire. pot in which the burner is to be used. I Thespecific construction of the invention iniits present form, together with the advantages resulting therefrom, will be more particularly described with reference to the accomp anying' drawing, in which;

, Fig; 1 is a plan view of the invention with portions broken away, the furnace structure being shown in section;Fig. 2 is a transverse section taken on the line 22 of Fig. 1; Fig. 3 is a vertical section taken longi tudinally of the gas supply conduit to one of the manifolds; Fig. 1 is an enlarged sectional view of one of the joints in the conduit.

The invention in its present form 'is adapted to be used in an oblong fire pot 5 and comprises a pluralityof manifolds 6, each having a plurality ofxspuds 7 inclined upwardly toward the wall ofthe fire pot.

Battles 8 are arranged above the spu-ds and as a convenient means for supporting these baflles, each baffie 'may be provided with a depending flange 9 which is adapted to be inserted between flanges or lugs 10 and 11' formed on the manifold 6.

Gas is supplied through a pipe 12 which leads to a head 13 adapted to'be supported from the bottom thereof. Inhorder that the manifolds 6 may be connected to theh-ead 13 and at the same time may be adjustable laterally to accommodate them to the width of the fire pot, it is preferred to form the head 13with outlet arms 14 having upturned ends 15 fromwhich the respective manifolds 6 aresupportedby a series of toggles. In the present instance,

50 each toggle comprises a pair of links 16 which The present embodiment of the invention, which is adapted to be used 1n anside wall of the fire pot or usted position and also to insure a. tight joint the toggle links.

of the ,fire pot centrally v manifolds the scope of the invention as are exactly alike andwhich-constitute a part ofthe' conduitthrough which the gas is. suppliedto the manifold. One end of the toggle is connected to the upturned end 15 0f the outlet arm 14f and-the'other end of. the toggle is connected to the downturned inlet mouthl? of the manifold. The links16 have coengagingends 18 and 19, one of which seats inside of the other, thelarger end of one link seatingon the outlet 15' and the smaller'end of the other link sea-ting within the manifold inlet mouth 17, whereby to provide a-togg'le having joints with vertical axes so that eachmanifold may be adjusted laterally to or from the longitudinally thereof: It isunderstood-,f of course, that suitable gaskets 20 may be provided for the severaljoints. i

' For I assembling the/toggles .sei-

curing them in their adjusted positions, each joint is provided with an axially disposed spindle 21,Ione end of which is threaded into a thickened portion 22 formed within one of the connecting members, theother end of the spindle projecting through a thickened por-. T5 tion 23 onthe other connecting member which is formed with a ground seat for receiving a nut 24, so that the nut may be tightened to secure the connecting members in any adthat will-not leak gas.

The space between baffles 8 and which is intermediately supported bylugs 26 formed on 8.5),

From the foregoing description, it will be seen that I have provided a-construction' by which the burner may be readily adjustedto' accommodate it to any size of fire pot. While in the construction shown, the gas to the is supplied through the toggles which support the latter, the invention is i not necessarily limited to such a 'const-ruc-' tion. The construction of the means by which l.

the manifolds are. supported. may also be modifiedwithout departing materially from claimed.

What I claim is: V 1. A gas burner comprising a the manifolds is covered by a plate the edges-of which mayv rest upon the pair of op- 1 positely disposed manifolds, a central gas supply head, and conduits leading from said head to the respective manifolds, each con-- du'it being in a plurality of sections constituting a toggle which is adjustable to Vary the distance between the manifold and said supply head.

3. A gas burner comprising a gas supply head, a manifold, and a toggle connecting the manifold to said head, said toggle being formed with a gas passageway therethrough.

4. A gas burner comprising a gas supply head, a manifold, and conduit sections constituting the links of a toggle connecting said head to the manifold.

5. A gas burner comprising a gas supply head, a manifold, and a conduit made in a plurality of sections pivotally connected in series with said head and manifold respectively to constitute a toggle for adjusting the distance between said head and manifold.

6. A gas burner comprising a gas supply head, a manifold, a conduit connecting said head to the manifold, said conduit being jointed to constitutea toggle, each joint ineluding two laterally turned ends, one seating against the other,

a spindle constituting the axis of the joint,

and means associated with the spindle for locking the joint and at the same time sealing it against leakage of 'as.

a 7. A gas burner adapted for use in a fire pot and comprising a pair of oppositely disposed manifolds, a common supply head between the manifolds, an intermediate conduitsection between each manifold and the supply head, and a pivotal sealed connection between each intermediate conduit section and the head and manifold between which it is located, said manifolds being adjustable about the respective connections to vary the distance between said manifolds and adapt them to fire pots of different Widths.

8. A gas burner adapted for use in a fire pot and comprising a gas supply head, a pair of oppositely disposed manifolds, connections including an intermediate conduit section between each manifold and the supply head, and joints between each conduit sec tion and the head and manifold respectively, each joint including two laterally turned ends, one seating against the other, aspindle constituting the axis of the joint, and means associated with the spindle for locking the joint and at the same time sealing it against leakage of gas, said manifolds'being adjustable about the respective connections to vary the distance between said manifolds and adapt them to fire pots of different widths.

In testimony whereof I have hereunto signed my name to this specification.
